However, many companies rely on different software solutions to handle each channel, which leads to heterogeneous IT infrastructures and isolated data sources. Omni-Channel CRM is a holistic approach towards a unified view on the customer across all channels. This paper introduces three case studies which demonstrate challenges of omni-channel CRM and the value it can provide. The first case study shows how to integrate and visualise data from different sources which can support operational and strategic decision. In the second case study, a social media analysis approach is discussed which provides benefits by offering reports of service performance across channels. The third case study applies customer segmentation to an online fashion retailer in order to identify customer profiles."}],"user_id":"15504","publication":"Proceedings of the 36$^th$ International Conference on Conceptual Modeling (ER’17)","type":"conference","page":"69–78","volume":10651},{"user_id":"15504","title":"Customer Service in Social Media — An Empirical Study of the Airline Industry","abstract":[{"lang":"eng","text":"Until recently, customer service was exclusively provided over traditional channels.

Companies aim to provide a better customer ex- perience by offering more convenient channels to contact a company. In addition, this unburdens traditional channels which are costly to maintain.

As the first multi-objective approach in the area of liner shipping routing, we show that giving more options to decision makers need not be costly.

They are considered to be capable of massively distributing propaganda in social and online media, and their application is even suspected to be partly responsible for recent election results. Astonishingly, the term social bot is not well defined and different scientific disciplines use divergent definitions. This work starts with a balanced definition attempt, before providing an overview of how social bots actually work (taking the example of Twitter) and what their current technical limitations are. Despite recent research progress in Deep Learning and Big Data, there are many activities bots cannot handle well. We then discuss how bot capabilities can be extended and controlled by integrating humans into the process and reason that this is currently the most promising way to realize meaningful interactions with other humans. This finally leads to the conclusion that hybridization is a challenge for current detection mechanisms and has to be handled with more sophisticated approaches to identify political propaganda distributed with social bots."}],"intvolume":"         5","doi":"10.1089/big.2017.0044","citation":{"mla":"Grimme, C., et al. “Social Bots: Human-Like by Means of Human Control?” <i>Big Data</i>, vol. 5, no. 4, 2017, pp. 279–293, doi:<a href=\"https://doi.org/10.1089/big.2017.0044\">10.1089/big.2017.0044</a>.","bibtex":"@article{Grimme_Preuss_Adam_Trautmann_2017, title={Social Bots: Human-Like by Means of Human Control?}, volume={5}, DOI={<a href=\"https://doi.org/10.1089/big.2017.0044\">10.1089/big.2017.0044</a>}, number={4}, journal={Big Data}, author={Grimme, C and Preuss, M and Adam, L and Trautmann, Heike}, year={2017}, pages={279–293} }","short":"C.

Until very recently, these configuration procedures were limited to optimising a single performance objective, such as the running time or solution quality achieved by the algorithm being configured. However, in many applications there is more than one performance objective of interest. This gives rise to the multi-objective automatic algorithm configuration problem, which involves finding a Pareto set of configurations of a given target algorithm that characterises trade-offs between multiple performance objectives. In this work, we introduce MO-ParamILS, a multi-objective extension of the state-of-the-art single-objective algorithm configuration framework ParamILS, and demonstrate that it produces good results on several challenging bi-objective algorithm configuration scenarios compared to a base-line obtained from using a state-of-the-art single-objective algorithm configurator.","lang":"eng"}],"doi":"10.1007/978-3-319-50349-3_3","user_id":"15504","publisher":"Springer International Publishing","date_created":"2023-08-04T15:10:09Z","status":"public","language":[{"iso":"eng"}],"year":"2016","_id":"46364","date_updated":"2023-10-16T13:37:50Z","editor":[{"last_name":"et al.

In the context of single-objective, continuous optimization problems such knowledge can be retrieved by means of Exploratory Landscape Analysis (ELA), which automatically identifies properties of a landscape, e.g., the so-called funnel structures, based on an initial sample. In this paper, we extract the relevant features (for detecting funnels) out of a large set of landscape features when only given a small initial sample consisting of 50 x D observations, where D is the number of decision space dimensions. This is already in the range of the start population sizes of many evolutionary algorithms. The new Multiple Peaks Model Generator (MPM2) is used for training the classifier, and the approach is then very successfully validated on the Black-Box Optimization Benchmark (BBOB) and a subset of the CEC 2013 niching competition problems."}],"doi":"10.1145/2908812.2908845","place":"Denver, CO, USA","page":"229–236","_id":"46367","date_updated":"2023-10-16T13:38:47Z","date_created":"2023-08-04T15:14:06Z","publication":"Proceedings of the 18$^th$ Annual Conference on Genetic and Evolutionary Computation","status":"public","language":[{"iso":"eng"}],"year":"2016","publication_identifier":{"isbn":["978-1-4503-4206-3"]},"type":"conference"},{"issue":"2","date_updated":"2023-10-16T13:40:21Z","_id":"46371","page":"589–618","volume":64,"language":[{"iso":"eng"}],"year":"2016","type":"journal_article","status":"public","date_created":"2023-08-04T15:17:48Z","publication":"Computational Optimization and Applications (Comput.
